To alt whom it may concern:

Be it known that we, GEORGE E. SAVAGE and CHARL'as B. TRIPP, citizens of the United States, residing at Meriden, county of New Haven, State of Connecticut, have invented certain new and useful Improvements in Alcohol-Lamps for Chafing-Dishes, &c., of which the following is a full, clear, and exact description.

This invention relates to improvements in lamps, and particularly to an alcohol-lamp for chafing-dishes, &c. The main object of the invention is to provide improved features of construction, whereby the flame may be regulated and controlled to a nicety and whereby any excessive pressure within the font is automatically relieved. These and other features will be apparent to any one skilled in the art from a reading of the specification and an examination of the accompanying drawings, in which Figure l is a side elevation. vertical section. Fig. 3 is a plan view. Fig. 4: is a side elevation of a detail of construction. Fig. 5 is a section of another detail, enlarged.

1 is the lamp-font adapted to contain alcohol. In the main the construction of this font is well known and will therefore be only briefly described.

2 is the wick tray or receptacle which stands above the alcohol-space and is provided with a central filling passage or neck 3.

4 is a wick.

5 is a screen standing above the wick.

6 is a cap arranged to neatly fit the neck 3 after the font is filled. The center of this cap is provided with a valve-seat 7, arranged to receive a valve 8. The valve 8 is provided with a depending stem which very loosely fits the passage through said seat.

9 is the stem referred to, and 10 is a chain secured to the stem 9, which prevents the cap 6 from being lost when removed from the neck. The weight of the chain also aids in seating the valve 8. Should there be any excessive pressure within the font 1, the valve 8 will readily lift to relieve the same. The font 1 in the particular form of the invention herein shown is provided with a surrounding jacket 11, said font being properly centered thereon, as at 12. Above the font is a top piece 13, having a central aperture, the edge of the top piece adjacent said aperture being Fig. 2 is a turned upwardly to provide what we term the deflector 14.

15 15 are the usual shutters, operable by a handle 16. 17 17 are draft-ports, which serve to convey air to the base of the flame. In the particular form shown the air will follow the course indicated by the arrows in Fig. 2, following around the font l, thence up to and through the central aperture in the top piece 18 is a damper which may be suitably arranged relatively to the draft-ports 17 17, whereby the size of said ports may be modified. The damper is provided with openings which register with the draft-ports when in the proper position; but by turning said damper the size of the draft-ports may be modified.

Any suitable means may be provided to control the damper-for example, a handle 19, such as shown in Fig. 1, or a link 20, such as shown in Fig. 2, which connects said damper with the moving part of the shutter orshutteroperating device.

In operation we have found that an extremely hot flame is produced, the peculiar formation of the top piece and the draft-pas sages affording means which contribute to that end. For example, by furnishing the deflector 14L the inrushing currents of air from the sides do not choke the flame, but are deflected upwardly in the direction of the flame. Should the user desire to reduce the strength of the flame, this may be done either by modifying the size of the draft-ports, which supply air to the root of the flame, still allowing said flame to be approximately the same in diameter, or he may reduce the diameter of the flame by controlling the shutters.

It should be understood that we have de scribed and illustrated only one form which our improvement may take and that we contemplate that many modifications and changes may be made without departure from the scope of the following claims.

What is claimed is 1. In a lamp of the character described, a font or reservoir, an overstanding top piece spaced apart therefrom and having a passage for the flame, draft-passages near the lower part of said font for conducting air to the base of the flame before it emerges from said top piece, a damper for said passages, a separate shutter-damper arranged to control the size of the flame-opening, and means of connection between the first-mentioned and the secondmentioned damper whereby the movement of one Will be transmitted to the other and the size of the draft-passages varied in proportion to the variation in the size of the flame-passage.

2 In a lamp of the character described, a

font, a jacket laterally surrounding the font,-

valve-seat therein, a valve'adapted to said seat, and a stem on said valve loosely fitting said passage and extending below said cap, a retaining-chain attached to the lower end of said valve-stem.

I. In a lamp of the character described, a font for the fluid, a Wick-tray in the upper part thereof having a filling-passage leading directly to the font, a screen above the Wickt-ray, an overstanding top piece having an eX- ternally-concaved upturned flange surrounding a central aperture, means for admitting air adjacent the base of said font and discharging it above said screen at the base of the flame, and swinging shutters for regulating the exit for the air and flame.
